Today, 75-80% of the world's natural diamonds are used for industrial purposes and 20-25% for gemstones. It is the chemical and physical properties of this mineral that give it the superior cutting ability for industrial use. Diamond coatings have improved on diamond's industrial applications in cutting and in aiding the performance of semiconductors. It is the optical properties of this mineral that give it the superior beauty and durability to be used as a gemstone. The rarity of this gemstone is related to the pet
rogenesis of the igneous rock in which the diamond is recovered. Diamond may even be found in meteorites. It is an important economic resource, responsible for developing nations and creating war. Faceting diamond, in order to maximize its optical properties, depends upon a knowledge of geometry. Diamond is the perfect mineral to focus on considering its notoriety and the fact that diamond studies cross disciplines, such as mineralogy, geology, astronomy, material science, mathematics, anthropology, art, history, and economics.
